1 Claims.

'lhe'ob'je'ct of the invention is to provide improvements in devices for applying paste or other liquids and semi-liquids to webs of various sorts,

but more especially to strips or lengths of wallpaper and the'like.

Another object is to provide insuch a device means for so regulating the rotation of what will be termed the paste-applying roll that in passing around a portion of its surface the paper web will slip or move with respect thereto.

A further object is to provide an improved weight for the device, so constructed as to permit its remaining in inoperative position, or to rest in operative position when desired, but in spaced relation with said roll, in such latter position being operative to yieldingly retain the paper web in predetermined frictional cooperation with said roll. 7

Still another object is to provide in such device "an idler roll, operative to maintain the paper web in engagement with the paste-applying roll, but with end portions of less diameter than its central portion, said end portions being in normal spaced relation with the marginal portion of the web, to prevent the carrying of paste from one web to another.

And a still further object is to provide in this device a removable paste container, having at least one side composed of gauze through which paste isadapted to flow into the principal container into which the paste-applying roll extends.

With these and other objects in mind, the present invention comprises further details of construction and operation which are fully brought out in the following description, when read in conjunction with the accompanying drawing, in which Fig. l is a perspective view of one embodiment of the invention; Fig. 2 is a transverse vertical section of the same; Fig. 3 is a perspective view of the paste container; and Fig. 4 is a similar view of the roll regulating spring.

Referring to the drawing, a'container comprises a bottom 1, end walls 2, and front and rear walls 3 and 4, respectively. A paste container or reservoir, shown per se in Fig. 3, comprises an annular relatively stifi? frame 5, having spaced depending lugs 6 for detachable engagement with the end and rear walls of said first container, while depending from said frame is a preferably rectangularly shaped gauze or equivalent body portion 7, the essential feature of which is that theforward wall 8, that is the one facing the front wall 3 of said first container, is apertured or formed of gauze, while the other walls of said paste container may be imperforate if desired,

' An angular spring, shown per se in Fig. 4,com-

' From the end walls 2 there arisespaced brackets 9 carrying lugs 10 and 11,'while supported by and extending between said brackets is a rotat able paste-applying roll 12, adapted to be rnanually turned when desired by means of a crank 12, while said roll also extends downwardly, into said first container in order tothere receive paste or other liquid which has flown into said first container from theso-c'alled paste container.

prisesa' free end portion 13 and a relativelyfixed screw 18, the forward wall3 of said container is preferably deflected inwardly to provide a flange 20 for a purpose hereinafter described.

Pivotally carried at 21 by the brackets 9 are two oscillatable arms 22 which by engagement with the lugs 10 are yieldingly maintained in an upper or retracted position, and by engagement with the lugs 11 are prevented from dropping below a certain predetermined angular position, Between these arms extends a rotatable idler roll 23, having conical ends 2%, while said arms are also connected by means of a strap or the like 25,

' to which is detachably secured a weight 26 and.

a preferably non-corroding angularly bent guard 27 The free edge portion 28 of this guard preferably rests against the weight 26, or is otherwise fixed with respect to the strap 25.

In the operation of the device a web 29 is threaded through the device, as shown in Fig. 2, so that it first passes over the wall flange 20,

thence-beneath theguard 27, over a portion of .100.

the surface of the roll 12, and thence beneath and partially around the idler 23. If the web is then drawn in the direction of the arrow, it will cause the roll 12 to rotate and thereby lift paste 7 or other liquid from said first container towards and spread it upon the undersurface of said web, the latter being maintained in frictional engagement with said roll by means of the weighted guard and idler. However, by properly adjusting the tension of the spring 13-44 by means of the screw 13,. the roll 12 while continuing to rotate will not rotate with as fast surface speed as of the web passing across its surface, and in this way the amount of paste or other liquid or semiliquid applied to the web may be accurately varied. Depending upon the relative stifiness, thickness, flexibility, or other structural characteristics of the web 29, the weighted guard is adapted to rise and fall and thus automatically maintain a substantially predetermined engagement of the webwith the paste-applying roll.

Having thus described my invention, what I claim and desire to protect by Letters Patent of the United States is:-

1. A web pasting device, comprising a paste container, a paste-applying roll extending into said container, a bracket carried by said container and rotatably supporting said roll, and a gravity-actuated Weight, oscillatably carried by said bracket and extending parallel with the axis of said roll, to frictionally engage a paper web and remove wrinkles therefrom and yield in accordance with the stiffness of such web to maintain said web in substantially uniform frictional engagement with said roll.

2. A web pasting device, comprising a paste container, a paste-applying roll extending into said container, a bracket carried-by said container and rotatably supporting said roll, and a weight oscillatably carried by said bracket and extending parallel with the axis-of said roll, to frictionally engage a paper web and yield: in accordance with the-stiffness of such web to maintain said web in substantially uniform frictional engagement with said roll, a wall of said container terminating in a curved flange in contact with which a web passes and also parallel with the axis of said roll, and said weight engaging the opposite surface of a web between said flange and said roll to further insure the removal of wrinkles from the web. I

3. A web pasting device, comprising a paste container, a paste-applying roll extending into said container, a bracket carried by .said container and rotatably supporting said roll, an arm oscillatably carried by said bracket, an idler carried by said arm, and a weight also carried by said arm parallel with the axis of said roll, a demountable member carried by said weight and providing a pronounced edge therefor, adapted to frictionally engage a paper web and with said idler retain such web in engagement with said roll, a wall ofsaid container being provided with a flange across and in contact with which the web passes and said weight engaging the web between said flange and said roll,

4. A web pasting device, comprising a paste container, a paste-applying roll extending into said container, a V-shaped spring, having its angular portion bearing as a fulcrum against one wall of said container and having one of its arms normally bearing directly against said. roll, and adjustable means connecting the other arm of said spring to said container wall and operative to vary the pressure of said first arm against said roll.
